Have patience. Knowing the Church of Scientology they'll be filing a lawsuit against the FIE for something or other any minute now.
I was gonna say, don't even try to sue the Scientologists -- those guys are scarily litigious. They're notorious for using prolonged litigation to harass and financially ruin their opponents.
And if that ad was a Girls' Club of America public service announcement promoting women's athletics or some such, it would've been awesome. Even if it was promoting Adidas athletic gear and showed their logo at the end, it still wouldn't have bothered me.
Problem is, nobody with a good production budget is out there making public service announcements promoting women's athletics, alas. The Scientologists can afford it, and GCoA can't.
